An Elk Grove resident was booked into jail Sunday after police said they found more than 100 marijuana plants, thousands in cash and an assault rifle in his home.

Firefighters were called to the house in the 6700 block of Vilamoura Way to put out a garage fire that was started by an overheated electrical connection that had been illegally tapped for power.

Elk Grove police officers arrived and detained the resident of the house, 26-year-old Christopher Michael Fernandez. Officers then obtained a search warrant, suspecting an illegal marijuana growing operation was somewhere in the living area of the home.

Detectives eventually found about 140 marijuana plants, 10 pounds of processed marijuana, $4,000 in cash, two loaded handguns and a loaded assault rifle, according to a police press release.
